Once HyperCard finds a handler for the message sent and begins performing the commands in a script, those commands are carried out sequentially from first to last.  You can modify the order or pass control using five control structures: If, Repeat, Exit, Send, and Pass.

If <true or false expression*> then
     <command>
     <command>
else
     <command>
     <command>
end if
